Review on 🔧 FIRSTINFO 3.4:1 Manual Torque Multiplier Wrench - 600 Nm - 1/2 inch Drive - Labor Saving Tool by Jarom Bulles

My 18" ratchet couldn't move the nut I put on the 18" breaker last week. I had to use the breaker attached to this tool to loosen the jam nut. If you rotate the device without a load, you will feel it being tightened in the same place with each rotation. Then, with additional effort, it goes into a phase of gentle rotation, and then tightens again. It seems to me that some gears have been mixed up. Either it is defective or the videos on YouTube are fake. Definitely coming back next week. Now we need to find a working replacement.
